CFX Expression for 95th percentile

RAJDEEP · November 27, 2019, 12:18

Hello everyone,
i am using CFX for my project work. I am having shear stress data on one of the wall.
i already knew about steps for finding 95th percentile shear stress after exporting it to excel or other some other software.

I want to know about, is it possible to use any cfx expression for 95 percentile shear stress on that particular wall and get it directly?
If any expression is there in that way, please let me know.

Thanks in advance

There is no built in function in CFX to do percentiles. If you want to do it in CFX you will have to write a user fortran routine to do it. Alternately you can just export everything and do it externally to CFX like you have been doing.

In CFD-Post there are options under file/export. You can select which object you export the data for, so it can be a contour object if you like.
